WebNote: Strictly increasing and strictly decreasing functions are one-to-one. Why? One-to-one function: A function is one-to-one if and only if f(x) f(y), whenever x y. CS 441 Discrete mathematics for CS M. Hauskrecht Identity function Definition: Let A be a set. The identity function on A is the function iA: A A where iA (x) = x. Example: WebTaking the cube root on both sides of the equation will lead us to x 1 = x 2. Answer: Hence, g (x) = -3x 3 – 1 is a one to one function. Example 3: If the function in Example 2 is one to one, find its inverse. Also, determine whether the inverse function is one to one.
